COCK.

SPECIFICATION forming part of Letters Patent N 0. 656,991, dated August28, 1900.

Application filed April 23, 1900.

T0 aZZ whom it may concern:

Be it known that 1, JOHN MORRISON, a citizen of the United States, and aresident of Dubuque, in the county of Dubuque and State of Iowa, haveinvented a new and Improved Cook, of which the following is a full,clear, and exact description.

This invention relates to a means for permitting the adjustment of theplugs of stop and waste cocks, so that the plug may be rendered right orleft handed in operation, according to the desire of the user or to theposition of the cock.

This specification is the disclosure of one form of my invention, whilethe claim defines the actual scope thereof.

Reference is to be had to the accompanying drawings, formin a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a side view of the invention. Fig. 2 is a plan View withparts in section on the line 2 2 in Fig. 1. Fig. 3 is a plan view of thecasing of the cock with the plug and cap removed. Fig. 4 is a bottomplan view of the cap. Fig. 5 is a side View of the top of the casing,and Fig. 6 is a section on the line 6 (5 of Fig. 4:.

The casing a of the cock is of the usual construction, being providedwith a waste-outlet a, as will be understood. The plug 1), which worksin the casing, may also be of the usual or any desired construction andis formed with the main passage Z1 therein and a wastepassage h all ofwhich parts operate as will be understood. It will be observed that thewater-passage b of the plug is considerably nearer the tapered or lowerend of the plug 1) than the waste-outlet a of the casing a, but stillabove the lower end of the main passage 1). XVith this construction thewaste-hole of the plug can never by any misadjustment be brought intoregistry with the waste-hole of the casing and so cause waste from thepres sure side.

The top 0 of the plug may be of any desired cross-sectional form, sothat the removablysecured cap d may be caused to turn there with. Thiscap is formed with a central opening d, conforming to the angular formof the top 0 of the plug, through which open ing the top of the plugpasses, the cap rest- Serial No. 13,923. (No model.)

ing on the top portion a of the casing a, so as to turn around the samewith the plug. The top a of the casing a is provided on its upper endwith two lugs a which are located diametrically opposite each other andare approximately equal in length to about oneeighth of thecircumference of the top of the casing. This proportion is, however,unimportant so long as the disposition of the opposite lugs limits thethrow of the plug to approximately ninety degrees of a circle. The lugsa bear against the under side of the top of the cap dand against theinner side walls of the peripheral flange of the cap, and the cap isprovided with two interior lugs (1 which, as indicated in Fig. i, aresituated opposite each other and bear against the edge of the top a ofthe casing, the lugs a and 61 being in the path of one another, so as tostrike when certain movements of the cap and plug are made.

When the cap is in place, one of the lugs (Z lies on each side of thetop of the casing, and as the cap is turned the lugs 01 willrespectively strike against the lugs a so as to limit the movement ofthe cap. In this connection it will be observed that when one of thelugs d strikes its corresponding lug a the other lug d will strike itscorresponding lug a on the opposite side. This arrangement willtherefore limit the movement of the plug and necessitate turning theplug ina certain direction, so as to open or close the same. Thereforeby changing the position of the cap on the casing the throw which it isnecessary to give to the plug will also be changed, and thus a cock maybe made right or left handed, as desired. The plug may be turned byahandle e of any sort, suitably connected therewith, and in theconstruction shown this handle is formed separate from the cap 61 and isreceived in a suitable socket in the plug, the handle and cap beingsecured by a a single set-screw f, which passes through the top 0 of theplug at a point above the cap (Z and engages the handle, as shown inFig. 2. The relative arrangement of the cap and handle or otheroperating devices, however, form no part of my invention, theessentiality of which lies in the relative formation of the cap and itsarrangement with the casing,as will be pointed out in the claim. It willbe seen in this connection that any two of the lugs taken togetherconstitute ninet degrees of a circle, and consequently that t 'e plug isal- Ways prevented from performing a greater movement. 4 r

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- The combination ofthe cock-casin g having a passage and provided with projections, withthe cap surrounding said projections and arranged to engage the casingwith its edge, the caphaving an interior lug adapted to engage the saidprojections, and an opening-of non-- circular shape, and a plug mountedto turn in the casing and controlling the passage thereof, said plughaving a portion passing through the opening of the cap and of the sameoutline therewith, the plug being securable to the cap in two differentpositions. In testimony whereof I have signed my name to thisspecification in the presence of two subscribing witnesses.
